How can I remove the exit button in a processing programs frame?

mcspud

Here is my code that only works when I press Esc, not when I click the stop button. When I click the stop button the pop-up box comes up, but the program closes after even if a press NO

public void exit() {
  exitOption = JOptionPane.showConfirmDialog(
  frame, 
  "Are you sure you want to exit?", 
  "Don't leave me!", 
  JOptionPane.YES_NO_OPTION);
  if (exitOption == JOptionPane.YES_OPTION) {
    super.exit();
  }
  else {
    exitOption = 0; // get rid of the box
  }
}

How can I get this code to work, or just how can I remove the exit button from the frame. The code working would be better but either way if fine. Please help!

Processing's IDE interfaces w/ the compiled program thru' network. Stop buttons sends an order to kill it!

Probably not what you're after, but this removes the frame decoration in its entirety.

void setup()
{
  size(200, 200);
  frame.removeNotify();
  frame.setUndecorated(true);
  frame.addNotify();
}

GoToLoop

That works for Java2D only. For the OPENGL based engines too:

/**

 * remove-decoration-window-under-p3d
 */

void setup() {
  size(400, 320, removeFrameBorder(P3D));

  frameRate(60);
  smooth(8);
  stroke(#00FFFF);
  strokeWeight(1.5);
  textSize(32);
}

void draw() {
  background(0300);

  fill(#FF0000);
  text(frameCount, width - 100, 40);

  fill(#0000FF);
  translate(frameCount % width, height >> 1);
  sphere(0150);
}

String removeFrameBorder(String gfx) {
  if (!isGL()) {
    frame.removeNotify();
    frame.setUndecorated(true);
    frame.addNotify();
  }

  return gfx;
}

@GoToLoop, I did not mean the stop button in the IDE! (lol) I mean the exit button in the window frame. I would like to remove it but keep the title bar (this is in windows). If you can't remove it then how can I detect if it is pressed so I can basically not count the press (so the program wont exit even if the exit button in the frame is pressed).

But thanks for info on the OPENGL thing, I didn't know that because I use JAVA2D for most things, might save me another question in the future. :)

Sorry, I dunno how to pull that out! Some possible solutions I've searched online involved instantiating a JFrame. :(
But Processing already got its own stored in frame! We would have to override that whole process to get any chance! X_X

Ok, that is what I found online too, I think I will just remove the whole frame with frame.setUndecorated(true); :-w I can always make my own exit button! :))
